Description

The The invention relates to a protection system according to the preamble of the claim 1 for camouflaging building roof areas.

Especially for sensitive objects, such as nuclear power plants u.s.w ,. is the Demand, the building roof areas like that equip, that the landing of helicopters, by means of which, for example, terrorists deposited on the building roof surfaces could become, is prevented.

Of the The invention is therefore based on the object, a protection system of initially mentioned type for roofs to create that is relatively simple and the landing helicopters on the corresponding roof surfaces prevented.

These The object is achieved by the Characteristics of claim 1 solved. Preferred embodiments or further developments of the protection system according to the invention are in the subclaims characterized.

With Help of the protection system according to the invention will - regardless of whether a wind is blowing or calm, simple means, i. avoided by a number of mist production facilities that the Building roof surface and the limiting the building's roof area Roof edges are visible, so that - after activation of the mist production facilities - helicopter landings be made impossible on the building roof surface. This is inventively characterized achieved that a number of mist production facilities on the If necessary, to be camouflaged building roof surface along the roof edge are spaced from each other, each Mist generation means a generated mist around a corresponding Section of the edge of the building roof diverting and the burnup flame of the respective mist generator is assigned to the top obscuring Nebelumlenkeinrichtung.

With Help the Nebelumlenkeinrichtungen is from the activated Mist generators emit fogs homogeneously distributed, so that not only the camouflaged building roof surface in its central area - of the Mist generating devices spaced - but also along the Roof edges, i. of the peripheral edge of the building roof surface, is distributed in such a way that the building roof area in total densely fogged and thus invisible from above, ie. is camouflaged.

A fog generating device of the type mentioned is, for example. In the earlier patent application DE 10 2005 004 935 described.

The Mist generation devices contain a misfit that is not is toxic and that does not cause corrosion, for example. From electronic circuits, contacts o. Like. Causes.

Is appropriate it, if the respective Nebelumlenkeinrichtung has a length, the at the distance between adjacent, at the corresponding edge the building roof surface arranged fog generating devices at least approximately adapted or shorter as this is.

The respective mist deflector is preferably with a roof element over the edge the building roof surface overhanging, so that from the simultaneously activated mist production facilities outflowing Mist around the edge of the building roof surface distributed homogeneously and thereby avoids that after activation the protection system according to the invention the roof edges or edges and thus the edge boundary of the building roof surface to be camouflaged visible remains. For this purpose, it has proved to be advantageous if the roof element of the respective Nebelumlenkeinrichtung frontally having a downwardly directed end element.

The respective mist deflector may comprise a back element, from the upper edge of the roof element towards the edge of the camouflaged Building roof surface away stands. Is appropriate it here, if the roof element from the back element obliquely upward is rising way.

The respective marginal Nebelumlenkeinrichtung expediently consists of a metal sheet with a planar roof element, a planar front element and a planar back element. Likewise, it is, for example, possible that the respective mist deflecting device consists of a part-cylindrical arched metal sheet. Of importance is that the fog generated by the respective activated mist generating device is deflected by the associated Nebelumlenkeinrichtung to the associated portion of the edge of the building roof surface to be camouflaged so that the roof edge total - regardless of the given wind direction and wind strength - densely fogged and thus invisible becomes. The surrounding roof edge also densifies the rest of the building's roof area. For this purpose, depending on the size ratios and dimensions of the building roof surface to be camouflaged, in addition to the edge-side mist generators, there may be additional mist generation from and apart from these facilities on the camouflaged building roof, be provided in the central region, each additional mist generating device is associated with a fog deflecting and the combustion flame upwards obscuring Nebelumlenkeinrichtung.

The respective central Nebelumlenkeinrichtung can a lateral surface element and a cover element, wherein the lateral surface element the associated Mist generation facility surrounds and with mist outlets is trained. The mist outlet openings are in the circumferential direction of the lateral surface element expediently equally distributed intended.

The mist-generating devices may be formed by mist pots, as in the above-mentioned earlier patent application DE 10 2005 004 935 are described.

at the protection system according to the invention it is preferred if all mist generation devices are for simultaneous activation, are operatively connected. The onset of action is e.g. Approximately 30 seconds after the simultaneous full-surface release of all mist production facilities. The fog duration after ignition may be, for example, about 30 minutes.

Further Details, features and advantages will be apparent from the following Description of an embodiment schematically illustrated in the drawing the protection system according to the invention to the desired camouflage a building roof surface.

It demonstrate:

1 a building roof surface with a protection system according to the invention, viewed from above,

2 a detailed view in the direction of the arrows II-II in 1 , and

3 a detailed view in the direction of arrows III-III in 1 ,

1 illustrates in a plan view of a building roof surface 10 with a protective system for camouflage, ie invisible, the building roof surface 10 , The protection system has peripheral fog generators 12 and additional central fog generators 14 on. The mist production facilities 12 are on the building roof surface to be camouflaged 10 along its peripheral edge 16 arranged equally spaced from each other. The additional mist production facilities 14 are on the building roof surface 10 from each other and from the peripheral fog generators 12 spaced apart.

Every mist generator 12 is a mist deflector 18 (please refer 2 ). The respective Nebelumlenkeinrichtung 18 indicates one of the building roof area 10 upstanding back element 20 , one from the upper edge 22 of the back element 20 obliquely upward rising roof element 24 and one from the front edge 26 of the roof element 24 downwardly directed end element 28 on. The respective Nebelumlenkeinrichtung 18 is dimensioned and positioned so that it with its roof element 24 over the corresponding edge 16 the building roof surface 10 survives free-standing.

The one after a simultaneous activation of the mist production facilities 12 generated fog is caused by the respectively associated Nebelumlenkeinrichtung 18 deflected and in the area of the exit gap 30 between the building edge 16 and the front element 28 homogeneously swirled.

The arrow 32 clarified in 2 a possible wind direction.

The from the exit slit 30 quasi-homogeneous swirling mist is due to the wind direction 32 in the direction of the arcuate arrow 34 around the mist deflector 18 deflected around the outside, leaving the building edge 16 by means of the mist production facilities 12 nebula, viewed from above, becomes invisible.

3 shows an additional mist generator 14 that a Nebelumlenkeinrichtung 36 assigned. The respective Nebelumlenkeinrichtung 36 has a lateral surface element 38 and a shell surface element 38 Upper side closing lid element 40 on. The lateral surface element 38 is with fog outlet openings 42 educated. The fog outlet openings 42 are in the circumferential direction of the lateral surface element 38 provided evenly distributed.

The cover element 40 hides the burn-off flame of the activated mist-generating device 14 in the direction of view from above. Accordingly, the roof element conceals 24 the mist deflector 18 (please refer 2 ) the burnup flame of the respective activated mist generator 12 in the direction of view from above.

The mist production facilities 12 and 14 are from fog pots 44 formed, as for example in the above-cited earlier patent application DE 10 2005 004 935 are described.

All mist pots 44 on a building roof surface to be camouflaged 10 are operatively linked together for simultaneous activation. This ensures that through the mist pots 44 not just the building roof surface 10 and the associated border 16 in the leeward direction of the wind is fogged, but also the roof edges 16 on the windward side. In addition, the combustion flames of the mist pots 44 when burned, they are not seen as bright points of light from the air.

By appropriate positioning of the mist production facilities 12 and 14 with the associated Nebelumlenkeinrichtungen 18 and 36 So both problems, namely the problem of fogging not only on the lee side but also on the windward side and the problem of invisibility of the combustion flames of the fog pots 44 solved.

The additional central fog generators 14 with the associated Nebelumlenkeinrichtungen 36 are used in particular for dense fogging of the building roof surface to be camouflaged 10 in calm weather.
